A B2B customer notices they have a large number of subscribers marked as ' Held...

The ' Held ' status in the All Subscribers list is a protective, system-managed state that Marketing Cloud automatically applies when a subscriber has accumulated excessive soft bounces, specifically to safeguard the sender ' s IP and domain reputation from being damaged by continuing to send to consistently unreachable or problematic mailboxes — and critically, this status cannot be changed directly by customer-side actions such as SQL updates, Contact Builder edits, or re-import, because it is deliberately locked at the platform/deliverability-infrastructure level, not merely a data field value the customer can freely rewrite. Re-enabling Held subscribers back to Active status requires contacting Salesforce Marketing Cloud Support directly, who can evaluate the situation and reset the status appropriately, since the restriction exists specifically to prevent customers from bypassing this deliverability safeguard on their own. Options A, B, and C all describe customer-initiated direct data manipulation of the status field — SQL updates, Contact Builder mass edits, or extract-and-reimport — none of which are effective or permitted mechanisms for resolving a Held status, since Held is enforced as a protective control rather than an ordinary, freely-editable subscriber attribute.
